1. Life
in a Coral Reef

2. In this lesson, you will discover:
1. Some of the animals found in a coral reef ecosystem.
2. The difference between carnivores, herbivores, omnivores, detritivores, decomposers, scavengers, and predator/prey.

3. eat other animals (prey). Prey are eaten by predators.
Sharks
Rays
Eels
Eat animals such as
Shrimp
Squid
Octopus

4. Carnivores such as: Eat other animals. Hawaiian Lionfish
Long-nosed Butterfly Fish
White Tipped Shark
Eat other animals.

5. Herbivores
such as:
Sea Urchins
Surgeon Fish
Eat only plants

6. Eat both plants and other animals.
Omnivores
such as:
Blennies
Crabs
Butterfly Fish
Eat both plants and other animals.

7. Feed on dead organisms (but not waste products).
Scavengers
such as:
Crabs (also omnivores)
Sharks (also carnivores)
Decorator Crab
Feed on dead organisms (but not waste products).

8. Eat parts of dead organisms and waste products.
Detritivores
such as:
Brittle Starfish
Sea Cucumbers
Shrimp
Eat parts of dead organisms and waste products.

9. Decomposers
such as:
Bacteria
- are organisms that return nutrients into ecological cycles by breaking down dead organic material.
Decomposers take all the material that is left over or further broken down by the detritivores and scavengers, as well as waste, and convert it to forms that are usable for algae to grow.

10. All of these organisms are interconnected in the Food Chain?
A food chain shows how each living thing gets its food. Some animals eat plants (herbivores), and some animals eat other animals (carnivores) others eat both (Omnivores). For example, a simple food chain links the phytoplankton, zooplankton, small fish, and then big fish. Food chains are linear.
Food chains demonstrate how animals & plants are related by the foods they eat.

11. Living Things Have Various Roles
Tertiary Consumer
Tertiary Consumers
Tertiary Consumers
Secondary Consumer
Primary Producers
Tertiary Consumers
All organisms in the ocean are interconnected either through a simple food chain, or a more complex food web. Food webs show how each organism requires the other in order to survive in an environment.
Decomposers
Secondary Consumers
Primary Consumers
These roles can be best defined in a food web.
